Notes: Owned by the City of Pittsburgh and operated by the Pittsburgh Stadium Authority. Two banks of ground level seats could be moved to reconfigure the venue for football. Constructed almost precisely on the site of Exhibition Park, which had been home to the MLB Pirates from 1891-1909. Named for its proximity to the confluence of the Allegheny and Monongahela Rivers to form the Ohio River at the “Golden Triangle”. Originally had Tartan Turf, which was replaced by AstroTurf in 1983.
